What is ZFS?

ZFS is a combined file system and logical volume manager. The features of ZFS include data integrity verification against data corruption modes, support for high storage capacities, integration of the concepts of file system and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair.

ZFS Hybrid Storage Pool

ZFS provides users with a Hybrid Storage Pool system by utilizing advantages of different storage types, including RAM, SSD (Solid State Disk) and hard drive. A hybrid storage pool consists of the following three elements: ZIL (ZFS Intent Log), Read/Write cache pool, and a high capacity pool. ZFS adopts the Adaptive Replacement Cache (ARC) mechanism, which temporarily stores operating data in RAM to improve performance. The cache data is controlled via two parameters: Most Recently Used (MRU) and Most Frequently Used (MFU). The second level cache, which is called Level-2 ARC (L2ARC), uses flash memory (such as SSD) to accelerate READ access (SSDs can also be used to increase the performance of WRITE access). ZFS Intent Log (ZIL) and Separate Intent Log (Slog) are both written to SSDs. EonNAS 3000 series* storage systems support SSD to improve the performance of applications with frequent random READ operations.

Unlimited Snapshot

The snapshot feature available on the EonNAS can be used to protect shared folders, iSCSI volumes and system settings. EonNAS supports an unlimited number of snapshots at intervals as short as 10 minutes. In addition, users can automate processes including snapshot creation and pruning. Snapshots will be automatically removed when they reach thresholds in terms of total number of snapshots or retention period.

Pool Mirror

To mitigate a disaster's impact on business continuity, data loss and downtime have to be minimized. The built-in pool mirror function on EonNAS helps users perform real-time data replication between two different EonNAS. When the primary system goes down, the standby system, which features the same data, can seamlessly take over services at minimized downtime.

Encrypted Remote Replication

This prevents your sensitive business data from being stolen by unauthorized breach or access. Even when processing remote monitoring/backup, EonNAS offers Encrypted Remote Replication by Rsync (with 128-bit SSH) to make sure the end-to end data security.

Corrupt Data Self-Healing

End-to-end data integrity requires that each data block be verified against an independent checksum. ZFS uses its end-to-end checksums to detect and to correct silent data corruption. If a disk returns bad data transiently, ZFS will detect it and retry the read. If the disk is part of a mirror or RAID group, ZFS will both detect and correct the error: it will use the checksum to determine which copy is correct, provide good data to the application, and repair the damaged copy.

RAID Protection

EonNAS features RAID protection, which ensures data stays intact even during simultaneous failures of up to two disk drives. When a drive failure occurs, a pre-assigned Hot Spare will be automatically leveraged to rebuild the original RAID configuration. In addition, Disk-Roaming Design enables disk drives be moved within an array, meaning when there is a need of system replacement, the hard drives within an array could be intact transferred to another EonNAS system and be automatically recognized without hard drives re-building concern.

WORM (Write Once, Read Many)

The WORM function prevents data from being edited, overwritten, corrupted or deleted until a retention period has arrived. WORM addresses the five elements of regulatory compliance: data integrity protection, data accessibility, data auditing, data duplication and data migration. EonNAS features secure data storage with flexibility to store both compliance-based WORM data and normal data for archive.

Simplicity

EonNAS satisfies diverse network storage needs at minimized management effort. System management for the EonNAS is simple. A user-friendly, web-based GUI allows you to easily access all frequently-used features via shortcuts and quickly complete required configurations with step-by-step wizards. EonNAS also supports a dashboard feature to help you monitor real-time system status.

Affordability

EonNAS requires very little training with simple installation and management, which keeps the overall IT budgets in check. In addition, EonNAS offers thin-provisioning which allows users to allocate a large amount of virtual capacity for an application server regardless of the physical capacity actually available.

Full-featured Business Applications

File Server

HTTP/HTTPS Server

The IT administrator can host multiple websites on the EonNAS with the built-in web server and virtual host feature.

Backup Server

Mac users are able to use Apple Time

Machine while Windows users can use third-party software such as Acronis Backup & Recovery to backup data.

FTP Server

One is able to establish an FTP server with the EonNAS and share files conveniently with colleagues or partners.

Storage Consolidation and Cross-Platform File Sharing

With comprehensive network protocol support on EonNAS Pro, files can be easily shared among local and remote workstations featuring Windows, Mac or Linux platforms. With the access control for folders and subfolders, you can easily deploy different instructions or status to monitor various workgroups or branch offices. You can also import account information from Windows Active Directory (AD) and LDAP Directory to EonNAS Pro, which makes it easier to configure accounts and authorization settings.

Optimal iSCSI and Virtualization Ready

The built-in iSCSI support on EonNAS Pro enables you to deploy IP SAN and to serve applications, such as mail servers, databases and virtualization. EonNAS Pro provides a seamless storage solution for virtualization servers such as VMware, Citrix and Hyper-V. In addition, the support for advanced MPIO and MC/S allows you to achieve data path failover, to load balancing and to enhance performance.

Efficiency

Explosive data growth in recent years has created a new set of challenges for businesses of all sizes: how to efficiently process all this data with limited budget resources? The new EonNAS reduces your primary storage footprint using compression.

Data Compression

SMBs can take advantage of data compression technology on the new EonNAS. Supported on both shared folders and iSCSI volumes, data compression on EonNAS is achieved with the LZJB algorithm, offering lossless and low-overhead compression.

Intuitive System Management Tools

System management for EonNAS Pro is easy, within less than 15 minutes you can complete the process from power-on to initial set-up. With step-by step wizards, a user-friendly, wed-based GUI helps you easily access all frequently-used features via shortcuts. The real time system with dashboard feature helps you monitor real-time system status, and if there is any potential purposed events occurred ,the instant notification via SNMP traps, and e-mail alerts will pass to you at the same time. You could also find the comprehensive event log, to track your online behavior.
